When you reach the train tracks, subway cars will zip back and forth as cops on the other side begin descending the staircase and firing on you. Kill who you can, and when your partners jump into the tunnel and begin running, you should do the same. Turn around to kill the cops and SWAT members that pursue you, but make it a top priority to run down the tunnel before the going gets too tough. At the end of the tunnel you'll find a staircase leading up (be sure to dodge the incoming subway car!) and the series of stairs will wind up back on the surface level where, you guessed it, even more cops are waiting.

There's no time to lose here. As soon as you surface, run towards the SUV parked alongside your location on the street. Ignore the cops in the area, since they'll replenish themselves constantly. Unlike the rest of this post-robbery section of the mission, you'll actually be able to boost this car and make a run for it. Your ultimate goal is to get back to Packie's place in Dukes, but you have to lose the cops before you can drop everyone off. Fortunately, as long as you don't do anything too heinous on the way back, your wanted level should go down to a much more manageable three stars. Just be weary of the roadblocks cops have set up on the bridges, which are the only real challenges in between you, Dukes, and a hell of a lot of money.
